Explore the historic Chateau at the Oregon Caves, one of the designated Great Lodges of the National Parks. Learn about the Monterey-style furniture, famous guests, and how the Chateau was brought back from the brink of disaster. Built in 1934, the Chateau at Oregon Caves National Monument is a rustic hotel in the Siskiyou Mountains adjacent to the entrance to the cave in the only active limestone formation in Oregon. The prime significance of Oregon Caves' Chateau lies in its designer's extraordinarily creative use of the limited building site and how he allowed the site to dictate major architectural choices. The Chateau is a six-story structure with a reinforced concrete foundation and a superstructure of wood frame construction with enormous post and beam interior supports. The building spans a small gorge and a great deal of the building's mass is banked into that depression. Exterior walls are shiplap siding sheathed with cedar bark, giving the building a shaggy, rustic appearance.
